4 Claims. (Cl.129-16.7)

This invention relates to visible indexes andmore particularly to .an insert adapted for use in card holders of the type where each card holder' has a paper sheet provided with a transparent sheath embracing the free marginl The invention comprehends the provision of a title insert for visible indexes that is provided with means to interlock with portions of the card 1 holder so that when the titleinsert is applied in its operative position on the card holder it will be normally retained against detachment from the card holder.

The invention further comprehends the provision of a title insert for visible indexes of the character having a sheet forming part of the card holder in which the free margin and normally visible portion of the sheet is provided with a protective transparent sheath embracing the free margin, so arranged that the insert strip will have portions thereof adapted to engage portions of the card holder in cooperative relation to normal- 1y retain the insert strip in the sheath. Specifically, the insert strip is comprised of an elongated narrow strip of sheet material having the is central portion of each end slotted longitudinally to provide shoulders at the opposite edge of the slots for engagement with shoulders provided on the card holder by cut-out portions at the corners of the free margin of the sheet. 30 In the drawing: Fig. l is a plan view of a conventional form of card holder for visible indexes showing the insert strip of this invention in operative position.

Fig. 2 shows an end portion of the free margin 36 of the card holder in perspective on an enlarged scale with portions broken away and shown in section to further illustrate the invention, the record card being omitted for convenience in illustration. 40 Fig. 3 is a cross section taken on line 3-3 of Fig. 1.

Fig. 4 is a horizontal cross section takenon line l-.4 of Fig. 1. The card holderindicated generally at l is of 45 conventional construction and a type'well known in the art, a plurality of these card holders being adapted to be mounted in ofiset overlapping relationin a tray in a well known manner, so that the freemargins of each card holder are arranged 50 in adjacent visible indexed relation. The card holder I has a supporting strip or lug 2 secured to one margin of a sheet 3 by means 01' stitches l. The sheet 3 is of less width than the length of supporting strip or lug 2 so that the ends of lug 65 2 may be engaged with the supporting flanges on a card index tray not shown. in a manner well known in the art. The margin of the sheet 3 se-- cured to lug 2 is provided with a row of perforations to form a hinge 5 so that the card holdin portion .6 is hingeable relative to supporting strip 5 or lug 2.

A record card 1 is held on one face of portion I 6 of sheet 3 at the upper corners by diagonal slot -8 through which the corners of the card are threaded. At the free margin of card holding 10 portion 6, card 1 is held by transparent tip or sheath 9.

Sheath 9 is formed of a strip of celluloid folded in the central portion and arranged to embrace the free margin of 'cardholding portion 6 1 throughout the width, of the sheet, the front edge of sheath 9 having an intumed lip l0 providing a rounded edge on the sheath to facilitate easy insertion of the record card in the sheath- The corner portions of card holding portion 6' 20 of sheet 3 are cut out as indicated at H and the endsof sheath 9 extend over these cut-outs II as clearly shown in Figs. 1 and 2. Wire stitches II have the lower ends engaged as indicated at l3 in Figs. 1 and 2 through the front and back folds of the celluloid strip forming sheath 9; and draw the front and back folds of the sheath 9 into close contact in cut-outll. The opposite end of wire stitches l2 extend upwardly in substantially parallel relation to theside edges of sheet 3 beyond the edge of sheath 9- where they extend through the material of sheet 3 as indicated at M. This method of attaching the sheath to sheet 3 compensates for differences in expansionbetween the material of the two parts which v are normally found to have different coemcients of expansion so that the wire stitches can pivot in the parts to which they are secured and permit relative expansion without buckling either the sheath or sheet 3. Cut-outs II at the comers of the free margins of card holding portion 6 provide 'shoulders 15 used in connection with the present invention An insert strip l6 formed of an elongated narrow strip of sheet material, such as paper, which is adapted to receive indexing information for the card holder useful in visibly indexing the card holder independent of record card I, is according to this invention of a length so that it will slidably engage between stitches I! of a card holder l with just sufilcientclearance to provide for the slidable'engagement and disengagement of the strip from sheath 9. The ends of strip I6 are slotted as shown at I! in the central portion at both ends, the slots extending 5s longitudinally of the strip. The portion of strip It at opposite sides of slot l1 provides shoulders on the strip that are adapted to engage shoulders I at opposite ends of the free margin of car holder I.

When strip I6 is to be used in the card holder, it may have suitable indicia applied on one margin thereof, and the strip then inserted into sheath 9 into the position shown in the drawing in which one edge of the insert strip will extend into the central fold portion of sheath 9 while the shoulders formed at one side of slots l1 on each end of the strip will be opposed to shoulders l5 of card holder portion 6 of card holder I. Due to the compressed relation of the ends of sheath 9, the ends of insert strip I'G engaged in sheath 9 will be curved rearwardly relative to card holding portion 6 into cut-outs H1 in sheet 3, and as a result the shoulders of insert strip IE will be aligned with shoulders i5 and adapted for cooperative engagement to normally prevent detachment of insert strip l6 from sheath 9. This provides for the retention of insert strip IS in sheath 9 under normal conditions of operating the index which will require the insertion and removal of record cards I from the card holder, possibly at frequent intervals. During the insertion or removal of a record card from the card holder or even several record cards that may be in superimposed relation on one face of card holding portion 6 this interengagement of the shoulders on the insert strip and card holder will retain the insert strip in attached position in sheath 9.

When it is desired to remove insert strip I6 from sheath 9 it may be done by grasping the central portion of strip IS with the thumb and forefinger, and giving the strip a quick jerk outwardly from the sheath, moving the strip toward the supporting lug 2 of the card holder. This, it has been found, will disengage the shoulders on the insert strip from the shoulders on the card holder without damaging either so that the insert strip may be subsequently reinserted in interlocked position in sheath. 9. In this operation of the insert strip and the card holder it will be noted that the record card I is of less width than the length of strip l'i so that the ends of the strip project sufllciently beyond record card to provide for the flexing of the end to engage the shoulders formed by slots l1 with shoulders IS.

The invention claimed is:

1. In combination, a card holder having a sheet formed with a card holding portion, a transparent sheath embracing the free margin of said sheet and secured thereto, shoulders provided on said sheet at the side edges in the region oi said sheath, an insert strip having shoulders formed on the ends adapted to cooperatively engage the shoulders on said sheet when said strip is inserted in said sheath ior normally retaining said strip in said sheath.

2. In combination, a card holder having a card supporting sheet, a sheath on the free edge of said sheet, said sheet having portions of the side edges adjacent said sheath notched to provide shoulders, an insert strip formed with shoulders for cooperative engagement with the shoulders on said sheet when said strip is engaged in said sheath. I

3. In combination, a card holder having a card supporting sheet formed with notches at the corners of the free margin to provide shoulders, a sheath embracing said free margin and said notches, fastening means engaging the ends of said sheath in said notches at one end and adjacent portions of said sheet beyond said sheath at the other end, and an insert strip slidably engaged in said sheath between said fastening means and having shouldered portions formed at the ends for cooperative engagement with the shoulders on said sheet to normally retain said strip in said sheath.

4. In combination, a card holder having a card supporting sheet formed with cut-out corner sections at the free margin forming shoulders spaced inwardly oi the free edge of said margin, a sheath of transparent celluloid folded over the free margin of said sheet and extending into said cut-out corner sections, wire stitches at each end of said sheath, one end of each stitch being engaged through the opposite fold portions of said sheath in its respective cut-out section and the opposite end of each stitch extending through said sheet beyond said sheath, said stitches securing said sheath to'said sheet and providing a card receiving pocket insaid sheath therebetween, said stitches also compressing the fold portions of said sheath together in said cut-out sections, and an insert strip having slotted ends to provide shoulders at the opposite sides of the slots at said ends slidably engaged between said ARTHUR REX JACKSON.
